I have plenty of spare Arduinos and ATMega168 chips.  No extra ATMega328s.

Nobody I know uses AVRstudio's writer; everyone uses AVRdude either
directly or indirectly (it comes with both the Arduino IDE and
CrossPack (nee AVR MacPack).

Have you tried starting the IDE, wiring up the ISP and then doing
Tools -> Burn Bootloader -> w/ AVRisp MkII ?  Works for me...  don't
forget to power up the Arduino via external power not USB before proceeding.
